ACPI: video: Add backlight=native DMI quirk for Dell Studio 1569
[ Upstream commit 23d28cc0 ] The Dell Studio 1569 predates Windows 8, so it defaults to using acpi_video# for backlight control, but this is non functional on this model. Add a DMI quirk to use the native intel_backlight interface which does work properly.
